Seriously, the previous owner didn't rev it above 4000 rpms??? What's the point of owning a 911 if you don't get the motor up spinnin' in the power band??
Red line is 6250 rpms on the '86. The ignition will cut out when you exceed it to protect the motor and auxillary equipment. Porsche recommends (from the owner's manual) that you don't rev a cold motor above 4400 rpms.
